Display before bootup

When I boot up there is no display. Literally nothing. The only time it shows display is when its fully loaded. Once the login screen is displayed its all fine, but nothing before it is displayed. This is an issue for me for many reasons; firstly, i’m trying to dual boot, and without seeing anything I can’t do anything. I can enter bios (I know that I’ve entered it because the screen doesn’t turn on at all, meaning its stuck in bios, sitting there, doing nothing). I’ve tried everything:

  • bootslash-manager
  • plymouth
  • editing /etc/default/grub

Output to cat /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash apparmor=1 security=apparmor udev.log_priority=3"

# If you want to enable the save default function, uncomment the following
# line, and set GRUB_DEFAULT to saved.

# Preload both GPT and MBR modules so that they are not missed
GRUB_PRELOAD_MODULES="part_gpt part_msdos"

# Uncomment to enable booting from LUKS encrypted devices

# Uncomment to use basic console

# Uncomment to disable graphical terminal

# format "root=/dev/xxx" instead of "root=/dev/disk/by-uuid/xxx"

# Uncomment to disable generation of recovery mode menu entries

# Uncomment this option to enable os-prober execution in the grub-mkconfig command

# Uncomment and set to the desired menu colors.  Used by normal and wallpaper

# Uncomment one of them for the gfx desired, a image background or a gfxtheme

# Uncomment to get a beep at GRUB start
#GRUB_INIT_TUNE="480 440 1"

# Uncomment to ensure that the root filesystem is mounted read-only so that
# systemd-fsck can run the check automatically. We use 'fsck' by default, which
# needs 'rw' as boot parameter, to avoid delay in boot-time. 'fsck' needs to be
# removed from 'mkinitcpio.conf' to make 'systemd-fsck' work.

If it happens even in BIOS, that’s likely a hardware issue. You should look for a BIOS firmware update first.

I cant update it if I can’t enter it


  1. This should work to enter the UEFI when logged in:
systemctl reboot --firmware-setup
  1. I would rather think that the keyboard is not fully initialized. Look for such options at the UEFI like “Fast Boot” and disable it.

I did this, the only thing that happened is it changed my desktop wallpaper to some color after it rebooted.

I think it is, normally when I boot up it just takes like 10 seconds, the keyboard has a white LED background, the background turns on and off a couple times. When I press F2 or F12 it doesnt continue into booting up, meaning something’s happened

You should be able to make the GRUB menu visible by editing /etc/default/grub to change:

But I do not see how that would help to make BIOS visible before the GRUB menu

The only thing I recall about being unable to view BIOS settings is that when the BIOS was updated or reset, the default monitor output setting in BIOS would revert from the GPU back to the motherboard onboard graphics.

It was like that before, and I’ll give that a shot again.

For some reason I think it’s linked to this, I don’t know why or how to change it but I think it is - The monitor goes on sleep mode, because it doesnt detect any output, and my cpu doesnt have integrated graphics, do you know how I would be able to fix this?
